Abstract

•The synthesis of new aniline-based squarylium dyes.•The effect of solvent on spectroscopic properties of p-substituted aniline derivatives of squarine dyes.•The effect of substituents on spectroscopic properties of studied dyes.

The synthesis and spectroscopic properties of series of new aniline–based squarine dyes have been presented. The effect of solvent polarity, hydrogen bonding and substituent on spectroscopic properties of 1,3-bis(phenylamino)squarine (SQG1), 1,3-bis(4-bromophenylamino)squarine (SQG2), 1,3-bis(4-ethylphenylamino)squarine (SQG3), 1,3-bis(4-ethoxyphenylamino)squarine (SQG4), 1,3-bis(4-nitrophenylamino)squarine (SQG5), 1,3-bis(4-chlorophenylamino)squarine (SQG6), 1,3-bis(4-iodophenylamino)squarine (SQG7), 1,3-bis(4-aminobenzosulfo)squarine (SQG8) 1,3-bis(4-methylphenylamino)squarine (SQG9) 1,3-bis(4-hydroxyphenylamino)squarine (SQK1) in ten selected solvents were studied.
